Writing to and Opening a Text File from an Apex Application

Hi there
I would like to open a text document from apex.
I have a screen with various parameters. Based on
what the user selects, the result must open a text
document with the parameters and other text.
Does anyone know a good way to do this?
Thanks
NorahUnless you start a Java widget, I do not believe you can modify a file on the local users machine through the browser. Now if the file is on the server you are running from, this can be done.
Thank you,

Viewing and printing a PDF file from Java Swing Application

Hello,
I need to view and print PDF files from Java Swing Application.How do I do that?I appreciate your help.
Thank you
Sumana Somareddy

If you have a link to the URL pointing to the PDF file, you can allow the browser to open it. Then use the print function of the browser to print the PDF document.

Opening a PDF file from a swing application in MAC

HI everyone,
Actually I am developing a swing application which should be executable in both windows and Mac (even other) platformes. In my panel I have an icon which leads to a pdf file. I saw in the following thread:
http://forum.java.sun.com/thread.jspa?forumID=17&threadID=617767
that we can use
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + file);to open what ever file in windows. I want to know what should I do if this application is running on Mac or Linux! I have never worked with these OS so I do not have any idea how to resolve the problem.
Can anyone help me with this matter?? That would be really nice of you to reply :)
Thanx and have a great day.

Thank you for replaying so soon..
Well you are right by using a widget and etc.. but the problem is that I have been told that this application should open a PDF file that has bookmarks to each chapter of the text and one can make a search on this text by using pdf search.. So I do not have any other choice than opening a pdf :D and my time is unfortunately limit.
For solving the problem that the user may not have PDF reader.. well I have been told that user should install the pdf reader, so in my application package I am putting the installation file of PDF.
But going back to my problem.. I guess is someway I have to get the OS type of the user and I have to do a SWITCH or something on the OS type and then change the content of the Runtime.exec(). But the question is how can I get the OS type and what should I change in Runtime.exec().
So now any idea? any solution??

How to download a text file from the server

hi everyone,
can anyone tell me how to download and read a text file from the server and saved in into resource folder.
with regards
pallavi

its really easy
To read from server, use something like:
HttpConnection connector = null;
InputStream inp_stream = null;
OutputStream out_stream = null;
void CloseConnection()
     if(inp_stream!=null)inp_stream.close();
     inp_stream=null;
     if(out_stream!=null)out_stream.close();
     out_stream=null;
     connector.close();
     connector = null;
public void getResponse(String URL,String params)
try
     if(connector==null)connector = (HttpConnection)Connector.open(URL);//URL of your text file / php script
     connector.setRequestMethod(HttpConnection.POST);
     connector.setRequestProperty("User-Agent","Profile/MIDP-2.0 Configuration/CLDC-1.1");
     connector.setRequestProperty("content-type", "application/x-www-form-urlencoded");
     //connector.setRequestProperty("charset","windows-1251");
     //*** If you need to send ("arg1=value&arg2=value") arguments to script use this:
     out_stream = connector.openOutputStream();
     byte postmsg[] = params.getBytes();
     out_stream.write(postmsg);
     int rc = connector.getResponseCode();//in any case here connection will be opened & closed
     if (rc != HttpConnection.HTTP_OK)
          CloseConnection();
          throw new IOException("HTTP response code: " + rc);
     inp_stream = connector.openInputStream();
     int pack_len = inp_stream.available();
     byte answ[]=new byte[pack_len];
     inp_stream.read(answ);
     CloseConnection();
     ProcAnswer(answ);//process received data
catch(Exception ex)
     System.err.println("ERROR IN getResponse(): "+ex);
} And you can read from resource file like
public void loadFile(String filename)
    DataInputStream dis = new DataInputStream(getClass().getResourceAsStream("/"+filename));
    String str="";
    try
         while (true)
            ch = dis.read();//read character
            if(ch=='\r')continue;//if file made in windows
            if(ch=='\n' || ch==-1)//end of line or end of file
                if(str.length()==0)continue;//if empty line
                //do some thing with "str"
                if(ch==-1)break;//it was last line
                str="";//next line
                continue;
             str+=(char)ch;
       dis.close();
   catch (Exception e)
       System.err.println("ERROR in loadFile() " + e);
}Welcome! =)

How do I get Adobe Acorbat to open a .pdf file from a sharepoint library without having to checkout the file

I have a customer that is using Adobe Acrobat pro version 10.1. When they try and open a .pdf file from a SharePoint site, the user is prompted to check out and open the file or open the file. Is there a way to get Adobe Acrobat to open the .pdf file without prompting to check out or open?
Thanks
Jim

This is mostly a lion thing, rather than a PSE thing. To disable applications opening where they left off last time for all the programs on your computer, go to system preferences>general and untick this box:
You can also do on a per-program basis, but it's more complicated and the best thing to do is to search around for directions on the web and see which way is least uncomfortable for you.
There's an odd little glitch in PSE that it opens the last image you had open, even if you closed it before quitting last time. Adobe says this is correct behavior, but of course it isn't.

Generating Text file from table using Shell script

I am using KSH for generating and FTPing a text file from a table.
While generating Text file I am not getting my Column names in orderly manner.
q2="select COLUMN1||' '||COLUMN2||' '||COLUMN3 from table1;"
set pagesize 0
set head off
set trimspool on
set trimout on
set colsep ' '
set linesize 1500
set trimspool on
spool /ss/app11/oastss/reports/$file2
select 'COLUMN1'||' '||'COLUMN2'||' '||'COLUMN3' from dual;
$q2
spool off;
EOF
I am getting the result some what like below in text file
COLUMN1 COLUMN2 COLUMN3
MALLIK_ACCT     17-SEP-11     908030482
MALLIK_ACCT     17-SEP-11     908266967
MALLIK_ACCT     17-SEP-11     909570766
I want the format like below
COLUMN1........ COLUMN2 .... COLUMN3
MALLIK_ACCT ...17-SEP-11 .... 908030482
MALLIK_ACCT ...17-SEP-11 .... 908266967
MALLIK_ACCT ...17-SEP-11 .... 909570766
I put dots(.) for illustration purpose.
column data length may icrease some times . it shoudl automatically adjust column and data so that they are in alignment. thanks in advance.

Reading and writing to a text file from an Applet

I'm a novice java programming with very little formal programming training. I've pieced together enough knowledge to do what I've wanted to do so far...
However, I've been unable to figure out how to read and write to a text file from an Applet (I can do it from a normal java program just fine). Here is a simple example of what I'd like to do (you can also look at it on my website: www.stat.colostate.edu/~leach/test02/test02.html). I know that there is some problem with permission/security but I'm not smart enough to understand what the error messages are telling or understand the few books I have. If anyone can tell me how to get this applet to work, or direct me to some referrences that would help me out I'd really appreciate it.
Thanks,
Andy
import java.applet.Applet;

import java.awt.event.*;
import java.util.*;
import java.io.*;
public class test02 extends Applet {
public Button B_go;
public GridBagConstraints c;
public void init() {
this.setLayout(new GridBagLayout());
c = new GridBagConstraints();
c.fill = GridBagConstraints.BOTH;
B_go = new Button("GO");
c.gridx=1; c.gridy=0; c.gridwidth=1; c.gridheight=1;
c.weightx = c.weighty = 0.0;
B_go.addActionListener(new ActionListener() {

File f = new File("test02.txt");
PrintWriter out = new PrintWriter(new FileWriter(f));
out.print("This is test02.txt");
out.close();
}catch(IOException e){**/}
}

I have almost the exact same problem, and I am in the same situation as you are with respects to the language.
I am simply trying to create a file and output some garbage to it but my applet always spits back a security violation. I've tried eliminating the restrictions on the applet runner I use but I still get the error.
My method:
debug = new Label() ;
debug.setLocation( 20, 20 ) ;
debug.setSize( 500, 15 ) ;
add( debug ) ;
// output
try
     OutputStream file = new FileOutputStream( new File( "" + getCodeBase() + "output.txt" ) ) ;
     byte[] buffer = { 1, 2, 3, 4, 5 } ;
     file.write( buffer ) ;
     file.close() ;
} catch( Exception e )
     debug.setText( e.toString() ) ;
     Can anyone tell why this isnt working?

How to upload a text file from a shared folder and provide an o/p

how to upload a text file from a shared folder and provide an o/p containing the details in each order in the text file

Hi,
Use GUI_UPLOAD to upload a text file from a shared folder.
Use GUI_DOWNLOAD to download data in a file on the presentation server or use OPEN DATASET, TRANSFER and CLOSE DATASET statements to download data to the application server.
Now, I hope the code for data fetching, if required, is already present in the report.

Opening a text file in server from an applet running in the client

Friends,
I want to open a text file in the server(The server machine uses tomcat 4.1.12 server)from an applet running in the client machine;
The applet invokes a servlet that opens the text file;this text file is opened in the server machine; but I want it to be opened in the client machine where the applet is running.
Plese help me to get around this.

You can open the textfile on the servlet and then send the information to the client (applet) as stirngs. The must then applet convert the stirngs into some object or simply display the information in someway. But then the text file that you are opening must be stored in some relevant tomcat directory e.g. on the server. If you want to open a file on the clients computer, you get into signed applets.

I open a donwloaded file from an e-mail and a file conversion box appears.The characters are all wierd.

I can not open a downloaded file from an e-mail or off the web w/o a file conversion box popping up.It shows options to open with msoffice word but I choose that and it opens with all the characters that are weird looking. There is also the issue where every time I open up Mozzila there are portions of advertisements that look like they are in Japanese. I go to the View in the top bar then select Character Encoding.The unicode is selected so I switch to Western (ISO-8859-1) and everything is normal. I close the browser and restart and it goes back to the way it was with the Japanese looking text.

You can convert the PDF text to regular text (.txt) and then import/open into another program and make your changes, then save the file in the programs format (for your later editing) and then choose Print from the program and there may/may not be a option to save as PDF again.
You'll need a free (limited use) PDF to text utility like
PDF OCR
http://solutions.weblite.ca/pdfocrx/
Trouble here of course is you lose all the formatting and have to reformat, but it's a lot less expensive than Adobe's software.
LibreOffice is free to use and can save as PDF format if iWork doesn't save as PDF, it should unless Apple is really peeved at Adobe.

When i open an mp3 file from a source other than apple, does itunes create it's own file and can I then delete the original mp3?

when I open a music file from a source other than apple, does itunes create it's own file and can I then delete the original mp3?

If you use iTunes' default settings then when you add a file to iTunes it places a copy of the file in the iTunes media folder and it leaves the original in place. The exception is when you drag it to the Automatically Add To iTunes folder.
It does not convert the file. You can delete the original if you wish.
